Madrid-based 3D artist Lee Griggs created some fascinating topographical illustrations using 3D animation and rendering software Maya Xgen and Arnold. Each piece is comprised of countless spheres, cylinders, or cubes that have been extruded and colored to create images reminiscent of ocean floors, bacterial growth, or even weather patterns. Griggs talks a bit more about how he renders these and shares a number of tutorials over on his blog. (via Colossal Submissions)
